The Venetian is without question the standard for room quality. A ton of room between tables, very comfortable chairs, and a nice atmosphere. This really is a perfect room.
I only played in the noon $150 tournament and the table was pretty standard. I can't speak for the cash games.
Dealers kept the game moving efficiently and were extremely friendly.
Drinks were fast enough and the coffee is the best I had in Vegas!
Nice electronic lists and were quick to point me to the correct area. The gentlemen who signed me up for the tournament wasn't very friendly, but that could easily be an isolated incident.
Not sure as I only played the tournament.
